ABSTRACT

Phytohormones play a key role in the regulation of growth, development and sustainability of the plants. Phytohormones of microalgae are considered as exogenous growth regulators, affecting the tolerance to factors of abiotic and biotic stress, as well as endogenous components of microalgae affecting the processes of biosynthesis of pigments and lipids. The review analyzed and summarized published data about the peculiarities of different classes of plant hormones formation and their impact on the growth and development of microalgae. The role of auxins, abscisic acid and ethylene in the regulation of growth processes and the development of resistance to abiotic stressors in different species of microalgae are discussed.
